CIGARETTE MACHINERY.

SPECIFICATION forming part of Letters Patent No. 565,852, dated August 11, 1896. Application filed July 2, 1894-.- Serial No. 516,255. (No model.)

To cbZZ whom it may concern:

Be it known that I, HUGO BILGRAM, a citizen of theUnited States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in CigaretteMachinery, of which the following is a true and exact description, reference being had to the accompanyin g drawings, which form a part thereof.

My invention relates to mechanism for making cigarettes, and particularly to the mechanism for molding a filler of definite length preparatory to inserting it into a cigal'ette-tube. I may further say that my invention is particularly, though not exclusively, adapted for molding fillers into conical shape.

The object of my invention is, generally speaking, to provide improved mechanism for molding cigarette-fillers with rapidity and precision, and my improvement consists in improved mechanism for feeding the molds, in improved molds and ways of arranging and carrying the same to improved devices for discharging-the formed fillers from the molds, in swabbing mechanism for cleansing the molds prior to use, and in various mechanical devices for operating the molds in connected part-s.

The nature of my improvements will be best understood as described in connection with the drawings, in which they are illustrated, and in which Figure 1 is a side elevation of mechanism embodying my improvements; Fig. 2, a plan view thereof; Fig. 3, a eross-sectional elevation on the line 1 1 of Fig. 2; Fig. 4, a crossseotion on the line 7 7 of Fig. 3; Fig. 5, a face view of the cam indicated at q. Fig. 6 is a cross-sectional elevation on the line 2 2 of Fig. 2. Fig. 7 is a perspective view of two coacting die-sections between which the filler is brought to shape. Fig. 8 is a similar view of the die-sections, showing them closed together. Fig. 9 is'a perspective view of the conical cigarette-filler molded in the dies. Fig. 10 is a plan view, on an enlarged scale, of a part of the mold carrying and operating mechanism, partly sectioned to clearly illus- Fig. 11 is a cross-sectional view on the line 3 3 of Fig. 10. Fig. 12 is a plan view of a detail of construction. Fig. 13 is a plan view illustrating various details of the apparatus situated below the mold-carrying table. Fig. 14. is a crosssectional view on the line 5 5 of Fig. 15, shown on an enlarged scale. Fig. 15 is an elevation of the swabbin g, carrying, and operating mechanism. Fig. 16 is a perspective view of the deviceused in operating the swab. Fig. 17 is a plan view of the wheel or table upon which the molds are carried, Fig. 18 being a cross-section on the line 8 8 of Fig. 17, and Fig. 19 a cross-section on the line 9 9 of Fig. 17.

A indicates the frame of the machine.

B is a bracket resting on and secured to the frame A, and from which depends a sleevebearing B for the table-carrying shaft 0.

B? B indicate bracket-arms extending out from the sleeve-bearing B, and to which are secured the stationary parts of the hopper P and of the slide-guides to be hereinafter described. From the lower part of the sleevebearing 13 extends an arm B to which is secured, by means of the arm I and plate I, the shaft-supporting sleeve 1 O is a shaft having a bearing in the sleeve B and supported on the top of this sleeve by the plate D, secured to the shaft by the pin (1 as shown. The shaft is given a reciprocating oscillatory movement by means of the lever-arm O, secured to its lower end and connected through the pivot-joint G with the rod C having secured at its other end a crankpin C on the crank-disk G which disk, as shown in Fig. 1, is secured on the shaft 0, said shaft being operated by means of miterwheels from the main driving-shaft Q and driving-pulley Q The plate 'D, as already men tioned,is pinned to the shaft 0, so as to move with it, and forming a part of or connected to this shaft is a lever-arm D, having at its outer end a pawl d, which is arranged to engage with notches formed on the under side of plate G (hereinafter described) and to reciprocate with the shaft 0. d (see Fig. 1) indicates another pawl placedto engage the said notches in the plate G or circular rack that is engaged by the pawl d; but this pawl is stationary in- ICO stead of reciprocating, as is the case with the said pawl d. Concentric with the shaft C, but not secured thereto, and resting on the plate D, is the flat circular plate G, having, near its outer periphery, teeth G, spaced and arranged to be engaged by the pawls d and d. Above this plate or table and secured to it is the plate H, which, as shown, is centered on the shaft C by means of its hub H, but which, as in the case of the plate G, is not secured to the shaft. The plate H is preferably made by casting, and for convenience I form it in the mold with annular spaces H and H for convenience in planning out the guidegrooves H and H lhe plate H is also formed with a groove H on its upper face to give access to the cam-face of the plate E, to be hereinafter described, and is formed with elongated cavities H to give access and play to the cam-rollers K. These cavities, at least in part, must extend through the plate, as indicated at H Fig. 11, so that the stems K of the cam-rollers K can be connected to the mold-slides below.

Z indicates a narrow groove formed on the under side of the plate H for a purpose to be hereinafter described.

F F, &c., indicate aseries of mold-sections permanently secured in the grooves H of the plate H, F indicating the curved mold-face and F F pinholes extending through the body of the mold or die section to the mold-face.

J is a plate secured to the under side of the mold-sections F, and. having an edge J, which extends somewhat in front of the edge of the mold-face itself.

L L, &c., indicate a series of slide-bars fitting and moving readily in the grooves H of the plate H, and having at their outer extremities mold-sections L, which fit and move on the inside of the slots or grooves H The curved mold-face of this section is indicated at L ll indicating pinholes extending through this mold-section and Z Z indicating cavities in the sides of the slides L for the insertion of pins adapted to extend through the inner holes Z of the die-section L. indicated in position in Fig. 10 of' the drawings at Z r the inner ends of the pins being bent and inserted in the grooves Z of the plate H. The other pins (indicated at Z Z, the.) are simply secured in place by being forced into holes bored in that portion of the plate H which faces the grooves H Both the pins Z and Z are, it will be observed, stationary with respect to the plate H, and they either do or do not project from the mold-sections in accordance with the backward-and-forward motion which is given to it. As shown, pins K are secured to the slide-bars L and extend up through the slots or openings H of the plate H, these pins serving as the bearings for the cam-rollers K, which lie in the cavities or recesses H of the plate H and through which a forward-andbackward motion is given to the slide-bars and mold-sections carried on the ends thereof.

Such pins are E indicates a plate secured as by a pin or key 6 to the shaft 0, so as to oscillate therewith. The outer edge of this plate is of irregular contour at the points indicated by E E and E (see Fig. 2,) the portion of the edge between the points E and E in one direction, coinciding with the circumference of a circle drawn from the center of shaft 0 (except at the point E and is indicated in the drawings by E, while the portion of the edge of the plate E, in the reverse direction, between the points E and E coincides with the circumference of a circle of greater diameter, but drawn from the same center, and is indicated in the drawings by E. For convenience these projections and depressions in the edge of the plate E are designated as cams E E, E, E and E and they are arranged on the edge of plate E, so as to register with or engage the rollers K.

is a short cam projecting from the part E of the edge of plate E about midway between the cams E and E and operates to engage the cam-rollers K to momentarily close the mold-sections upon the inserted swab, as hereinafter described.

Y is an arm secured to the plate E and having at its outer end a cam-section Y extending down so as to engage the cam-rollers on the outerside.

M is a friction-plate lying upon the top of the plate H, but secured to the plate E as by pins M so as to turn or oscillate with said plate. It is held against the plate H with the desired frictional force by means of springs M M, arranged to act between the plate E and the said friction-plate.

The operation of the parts already described is as follows: At each forward motion of the shaft 0, or motion in the direction of the arrow, (see Figs. 1 and 3,) the pawl d engages one of the teeth G of the plate G and causes said plate, together with the plate H, secured to it, to move forward through an are equal to that traversed by the shaft. When the shaft 0 begins its backward motion, the pressure of the friction-plate M upon the plate H is sufficient to cause the said plate to move backward slightly with the shaft until the teeth G are engaged by the stationary pawl d, which pawl holds the plates G and H, co1n posing what I call the mold-carrying wheel proper, stationary until the shaft begins another forward motion. My reason for using the friction-plate M is to insure that the plates G and H do not move forward beyond the movement of the pawl d, and that the ratchetteeth G are forced into intimate contact with the stationary pawl d, whereby there shall be an exact registration between the molds and the unattached mechanism and especially an exact alinement of the pin-holes F and H with their respective pins. With each forward motion of the shaft 0 and moldcarrying wheel the sectional molds and the cams secured to the plate E move forward together and without affecting each other; but

at each backward motion of the shaft and plate E, attached thereto, the cam-face E is moved against a cam-roller K in immediate juxtaposition to it, forcing said roller, together with the slide-bar L and mold-section L, connected with it, outward, so that the mold-section is moved with respect to the stationary mold-section from the position shown in Fig. 7 to that shown in Fig. 8. The part E of the cam edge of plate E being of uniform distance from shaft 0 holds the roller and moldsection in the position shown in Fig. 8 until it reaches the camsurface E where it is released from the pressure of the cam E and is free to move backward, its backward motion being accomplished by devices not yet described. The cam E situated between the cam-faces E and E acts like the cam E to push out one of the movable mold-sections at each backward motion of the shaft 0 and its attached plate E, but the mold-section so operated upon is thrust in or back again by the wedge-like cam Y by the same backward motion of plate E and immediately after the operation of the cam E It will be observed that in the construction I have described the molds open upon the under side of the moldcarrying wheel, and this arrangement, while not absolutely necessary, I greatly prefer as facilitating the feed and discharge of the mold. I may also properly state here that I make my molds of the length of the cigarette for which the filler is intended and provide them with end abutments formed of the walls of the slots I-I said abutments serving to mold and pack the filler at the ends while the body is being molded bythe pressure of the coacting mold-sections. In this wayI am enabled to produce a filler of precisely the right size for-the shell or wrapper into which it is to be inserted, and which will require no trimming, and I produce a cigarette with well-filled and with even-appearing ends as well as a compact and well-molded body.

Another feature to which I desire to call attention is that in the case of molds adapted to produce conical fillers, such as that indicated in Fig. 9 of the drawings, the slots H are formed to exactly fit the stationary moldsections and so that the lower edges of the various mold-sections will lie in the same plane. This is best shown in Fig. 1 of the drawings. construction I have described, the lip J of the plate J, secured on the under side of the mold-section F and extending beyond the edge of the mold itself, will, when the movable section is closed upon the stationary section, overlap its edge as well. The function of this plate is to effectually close any opening on the under side of the closed sections of the mold, so as to insure that no filaments of tobacco will hang down and give, asit were, a beard to the molded filler.

Resuming now the description of the parts shown in the drawings, Pis a hopper, the

breadth of which is substantially equal to,

It will also be noticed that, in the the length of the mold, and is adapted to register with one of the molds, while the moldplate H is stationary, and immediately before its movable section comes under the action of the cam-face E The rear wall P of the hopper is formed so that its top edgewill lie close to the under side of the movable mold-section L, the front of this edge registering with the front edge of the'said moldsection when it is drawn back, as indicated in Fig. 11.

P indicates a plunger forming, so to speak,

the front wall of the hopper and moving toward and away from the rear wall P, its forfront of the feed-plunger-R, the function of which will be hereinafter described. As shown, the plunger P is secured on the end of the pivoted lever P P indicating the pivot,

and the backward-and-forward motion being given to the lever and plunger by means of a cam Q, working against acam-roller P and secured to the main driving-shaft Q. As shown in the drawings, the bottom of the hopper is made up of a segment of a cylim drical surface drawn from the center of the pivot P.

R indicates a vertically-moving plunger reciprocating through an opening in the bottom of the hopper P and just in front of the rear wall P. It is secured to a slide R and actuated by the cam q, acting on' the camroller R secured to the bottom of the slide. The two-part mold F and L comes to register with the hopper with the movable section L thrown back, as indicated in Fig. 11. The feed-plunger R is then drawn down so that its top lies flush with the bottom of the hopper and the plunger P3 is drawn back, so as to leave the opening of the hopper free. A charge of tobacco is then thrown into the hopper P in front of the plunger P which is moved forward, compressing the tobacco between its face and the rear wall P, until it occupies the position shown in Fig. 11, where it comes to rest, and the plungerR then begins its upward motion, forcing the partly-compressed tobacco before it up intothe mold. When this is accomplished, the cam-surface E in the backward motion of.the plate E comes in contact wit-h the roller K and forces the movable mold-section L forward until the mold is closed and the tobacco firmly compressed between the two sections, the lip J passing beneath the lower edge of the diesection L and preventing the projection of any threads of tobacco below the mold. The next forward motion of the mold-carrying plate II brings another mold to register with the feed-hopper, the filled mold being held tightly compressed by the elevated surface E of the cam, which continues in operation until, in due order,the roller is released by the retreating cam-face E which permits the mold to be opened.

Passing next to the mechanism for opening and discharging the molds, (best shown in ward motion carrying it to a position just, in

IIO

Figs. 2 and 6,) U is a finger extending inward from a block U secured to the end of the lever U, which lever is pivoted at U andv the end of its arm U carries the cam-roller U which runs in the box-cam U secured on the main driving-shaft Q. Each inward motion of the lever U brings the finger U in contact with a roller K shortly after it passes the retreating cam-face E and the finger pushes the roller and the movable mold-section back to the position as indicated in Fig. 6, opening the mold. The backward motion of the movable mold-section causes the relatively stationary pins Z and Z to project from the curved face L of the mold-section L, so as to thrust the molded filler out from the mold-face. At the same time a series of pins U, which are attached to the block U are, by the inward motion of the lever-arm U, thrust into the holes F of the mold-section F for such a distance that they will project beyond the curved face of this mold-section and force the filler away from it. Preferably these pins U fit loosely in holes in the block U and have heads a, which rest on the outside of the block and are held in position by a clamping-plate U This construction I adopt in order to give the pins a certain amount of freedom. The pins Z, Z, and U serve to force the filler away from both mold-sections; but, as in my construction the fillers while molding are forced with considerable pressure against the end walls of the slots H in which the mold-sections are secured, it is desirable to have additional mechanism which will force the molded fillers downward out of the mold. For this purpose I form series of pin-holes H H in the plate H, so as to come above each end of the molded filler in the position it occupies when the molds are open, and I provide two sets of pins V V, (see Figs. 2 and 6,) which, after the molds open, are forced down through the holes II against the filler, which is by this means thrust entirely out of the mold and allowed to fall into or upon any convenient receiving device. The pins V are secured to a cross-bar V, attached in turn to the bent bracket or arm V the other end of which arm (see Figs. 3, 6, and 13) is attached to a slide V The pins are given a properly intermittent up-and-down motion by the action of the cam V acting on the cam-roller V secured to the slide V the said cam-roller being held in contact with the cam by the spring V Passing now to the mechanism for swabbing or cleaning the mold prior to filling, after the filler is discharged from the mold the mold in the consecutive action of the machine and still wide open is brought into register with a swab S. (Best shown in Figs. 10, 13, 14, and 15.) IVhile the mold is at rest in this position, the swab is forced up into it. This, in the construction shown in the drawings, is accomplished by the following mechanism.

The swab S is secured on the end of a springcured at S to a rod S having a yoke S which extends over the end of shaft 0, and a camroller S which runs in the box-cam S Arms S S (see Figs. 14 and 15) support a cross bar 8, which is engaged by a plate T and a spring-plate T, fastened to the plate T at T Fig. 16, the plate T being secured to a bracket T which bracket, as best shown in Figs. 3 and 13, is secured to the slide R, so as to move up and down with it. After the mold comes to register with the swab, the swab is thrust up into the open mold by the upward movement of slide E, the spring-plate T permitting a slight play or movement of the swab. After the swab has been thus carried into the mold the short cam comes in contact with the roller K of the movable mold-section and forces it outward, bringing the mold-sections toward each other, so that the swab is brought into contact with both mold-faces, the mold being held in this partly-closed position while the lever-arm S which carries the swab, is moved by its cam connections, and by its means the swab is given a longitudinal motion in the mold, wiping off any fragments of tobacco which may stick to it. As soon as this is accomplished, and it takes a very short time, the cam Y (see Figs. 10 and 11) comes in contact with the outside of the cam-roller K and forces the movable mold-section ack, thus releasing the swab, which is drawn down by the downward motion of the slide B, after which the mold is moved to register with the feed-hopper.
